| 摘要 |
The present invention relates to a method and apparatus for transmitting and receiving a discovery signal for detection between terminals in device-to-device (D2D) communication. The present invention transmits and receives a D2D discovery signal by determining a transmission pattern and a transmission group which is a transmission region of the D2D discovery signal, by using unique D2D terminal index information of each terminal. The present invention changes the grouping of the transmission group at each D2D terminal discovery signal transmitting and receiving unit (n) or updates a D2D terminal index to a different value when the D2D terminal discovery signal transmitting and receiving unit elapses N times. |
